England opening batter Crawley suggested he was not familiar with statements from captain Ben Stokes about the team environment as no place for "those lacking fortitude".
The all-rounder delivered those words in multiple conversations following England's loss in the second Ashes series versus the Australians earlier this month.
Ahead of the third Test, where the visitors now face defeat with a match to spare, the captain noted he had allowed his sentiment to "circulate freely" within the playing group.
"I have completed all the talking in recent days that I required," remarked Stokes.
But, following Crawley scored 85 on the fourth day in the third Test, he stated: "I didn't see that."
"I didn't see and wasn't really looking out for it. We take anything stated in the media with a pinch of salt," he added.
Raw Conversations and Steady Philosophy
Stokes issued his "weak men" observation after his side suffered a loss in the second Test to go two matches behind.
The England squad afterwards went on a break to Noosa between the second and the upcoming Tests.
Prior to the Adelaide contest, he revealed his players had held "honest" conversations and he had asked them to "display some fight" in their battle to stay alive in the series.
Nevertheless, the Kent batsman asserted the guidance from the captain and coach McCullum had stayed in line with their previous tenure in charge.
"It's been very positive, unchanged," said Crawley. "It's on maintaining positivity, playing our brand, with great liberty. We believed we could do an extraordinary feat going into this Test."
Australia Close of Historic Ashes Triumph
The opener's dismissal late on Saturday came during a decisive triple-strike by Australian spinner Nathan Lyon.
Lyon's three wickets in a short spell – including the wickets of Brook and Stokes himself – meant the chasing side 207-6 in pursuit of a notional total of 435.
Consequently, the home team need four wickets on Sunday's final day to move to an unassailable 3-0 lead after three Tests.
Defeat would prolong England's winless run in this country to 18 Tests and ensure a fourth straight overseas Ashes series defeat.
This series will be completed in just 11 days of play – after England fell the initial matches in two and four days respectively.
Not since 1921, when the Australians completed a series win in England in eight days, has the outcome of the urn been decided so quickly. The hosts have also triumphed in eleven days on two other occasions in the modern era.
"It's disheartening," said Crawley. "We came here to regain the Ashes and we're facing elimination at this point."
"There will still be plenty to play for and we will definitely view it with that mindset," Crawley added.
"The challenge has been difficult. Australia is a very, very good side. It was inevitably hard coming here against them. They entered as the front-runners and they've proven why."
Ollie Pope's Place In Question
Although the opener's performance in the third Test likely secures questions about his short-term future in the England team, Pope appears under threat for his position in the fourth Test on Boxing Day.
The Surrey batsman was out for 17 runs in the team's second innings on day four, extending his poor record versus Australia.
In sixteen Ashes knocks, Pope has failed to score a fifty and averages 17.62.
Only one other English batsman since 1900 – Dennis Amiss – has played an equal number of innings in the top order in Ashes Tests and returned a lower average.
However, Crawley insisted any suggestion Pope is under the microscope originates with "the media" – referring to the journalists – "not inside the camp."
"We all know how good of a player he is," said he. "He has had a good year if I'm honest."
"He has produced several excellent innings. This is noise externally. There is no chat like that on Ollie in the camp," he concluded.
